Initial support for building dists using mypyc. #15380
Conversation
Handles setting up mypy and any necessary config, requirements and type stubs, so that a preexisting setup.py can call mypycify(). Does not handle supporting mypyc in generated setup.py files. That will be provided in a future change. Also fixes a bug where we did not set the sys.path correctly when running a preexisting setup.py that imported code from a different source root. Also switches a test to use provides=python_artifact(), which is what we document, instead of the older alias setup_py(). [ci skip-rust] [ci skip-build-wheels]

Note that, hypothetically at least, we support multiple build environments. E.g., a single setup.py could use mypyc and (in the future) cython...

Should this be cherry-picked to 2.11 or 2.12? |

This is a pretty big rule, consider factoring out a @rule_helper. (Not sure that's the right call)

This whole file is huge and needs refactoring, but I will hold off on that for now.

What else would be relevant to a user? For example
- do we expect a hand-written setup.py / pyproject.toml? If so, with what content?
- clarifying it uses the version of
mypyfrom[mypy].version

Handles setting up mypy and any necessary config, requirements
and type stubs, so that a preexisting setup.py can call
mypycify().
Takes advantage of our existing robust support for mypy.
Lays groundwork for supporting other special build-time
requirements, such as cython.
Does not handle supporting mypyc in generated setup.py files.
That will be provided in a future change.
Also fixes a bug where we did not set the sys.path correctly
when running a preexisting setup.py that imported code from
a different source root.
Also switches a test to use provides=python_artifact(), which
is what we document, instead of the older alias setup_py().
